A new member of the class of S=1/2 triangular lattice quantum spin liquids will be studied with muons. It is obtained by replacing Cu with Ag in the original compound (ET)2Cu2(CN)3. A systematic set of studies in ZF, TF and LF will be carried out from 300 mK upwards on the CHRONUS instrument to complement lower temperature data being taken on MUSR and allow close comparison to be made with the Cu system and with a number of other triangular lattice spin liquids that were previously studied or are currently under study.
